Syllabus

The main objective of the course is to provide students with the basic knowledge and an introduction of organic materials and organic-inorganic hybrid materials relevant to materials science and biology and medicine.
Knowledge and understanding: Knowledge of weak bonds involved in the formation of organic materials. Understanding and application of the concept of self-assembling. Knowledge of the properties of materials in the nanometer scale. Understanding the structure-property relationship. Understanding how to change the properties of the material.
Ability to apply knowledge and understanding. The acquisition of this capacity is stimulated by the teacher during classroom lectures, critically presenting numerous applications; in the discussion of scientific works selected by the teacher; in preparation for the final exam.
Making judgments. The autonomy of judgment is developed during the lessons in the classroom and through the preparation for the exam, which requires the individual re-elaboration and assimilation of the material presented in class. During the lessons, evaluation and selected exercises are proposed and discussed concerning the most appropriate strategy for the preparation of a material or for the selection of a material for a specific application.
Communication skills. During the lessons the students are called to interact with the teacher also to acquire language properties and learn how to correctly express the concepts presented by the teacher. The student must also present a scientific work orally with the aid of a video projector presentation in a concise and effective manner.
Learning ability. the ability to learn is stimulated by the teacher during the lectures asking students to summarize the concepts explained in the previous lesson. Learning skills are assessed within the different evaluation methods described below.
